In some implementations, the cap panel 5 of the door can be fabricated with aluminum (Al) by die casting molding. As shown in FIGS. 5 through 7, such the die casting molding is proper to the complex shaped mold such as the cap panel 5 having the recess 6 with the closed side or the cap panel having the fixing projection 501 formed in the lower surface.

FIGS. 8-9 illustrate an example door of a refrigerator.

Referring to FIGS. 8-9, another example door of a refrigerator is described. The door includes the cap panel 5.

In some implementations, the cap panel 5 of the door may be fabricated by press die.

The press die means the molding method for forming metal products by installing a die in a press machine configured to reciprocate linearly.

If the cap panel 5 is fabricated by press die, it is difficult to fabricate the structure having the complex shape or projection and a cut surface is disadvantageously sharp. In contrast, the production cost is low and the production time is short advantageously.

The cap panel 5 may be also supported by the bending portion 4 of the door panel 3.

The fixing member 7 (or the pressing portion 77) may press the bending portion 4 in the internal space of the door panel 3.

The bending portion 4 may be fixedly arranged between the cap panel 5 and the fixing member 7.

The fixing member 7 (or the support portion 79) may support the inner surface of the door panel 3.

To fix the cap panel 5 and the fixing member 7 to each other may be applied the method of bonding the cap panel 5 to the blowing agent exposed through the fixing member 7 by providing the penetrating hole 705 in the fixing member 7 and another method of providing the adhesives or adhesive tape between the cap panel 5 and the fixing member 7.

In some implementations, the door may include a projecting portion 707 extended from the fixing member 7 and arranged between the cap panel 5 and the bending portion 4; and a stepped portion 709 stepped from one end of the projecting portion 707 and covering a cut surface of the cap panel 5. In some implementations, the fixing member 7 may include the projecting portion 707 and the stepped portion 709. The projecting portion 707 and the stepped portion 709 may be part of the fixing member 7.

The stepped portion 709 may be extended upward from the end of the protecting portion 707 and located on the same plane with the cap panel or higher than the thickness of the cap panel.

The stepped portion 709 may be provided as a groove for covering the end of the cap panel 5.
